libweston: Remove internal weston-log set-up function out of public header

We have dedicated header for the internal parts of the logging
framework, use that for the set-up part instead of the libweston public
API header.

Further more this removes weston_vlog() from public header as well and
moves them to weston-log-internal.h file.
